Abstract: A multi-functional electronic cigarette with a function of a laser pointer comprises: a battery module having a battery module, a display light; an electronic cigar switch and a laser pen switch; the electronic cigar switch and the laser pen switch being at an outer surface thereof; the display light being at a front end of the battery module; a laser module installed within the battery module; the laser pen switch serving to actuate and de-actuate the laser module; the actuation of the laser module will cause laser light to be emitted out from a front end of the battery module; a sucking portion including a control chip, a pressure sensor and an atomizer with liquid perfume therein; and the pressure sensor serving to sense pressure variation from the sucking portion so as to actuate the control chip and thus the control chip causes the perfume in atomizer to atomize.

Abstract: A blade assembly is connected to a robot arm for transmission of semiconductor chips and includes a blade, a top cover, a bottom cover, and two pivot units each including a pivot arm, a first bearing, and a second bearing. Thus, the positioning flange of the mounting ring of the pivot arm is sandwiched between the first bearing and the second bearing and the inner washer is sandwiched between the inner ring of the first bearing and the inner ring of the second bearing, thereby preventing the first bearing from pressing and jamming the second bearing due to a pressing action of the urging cap, so that the pivot arm is pivotable smoothly and stably.
